Application filed February 5, 1924. Serial No. 690,759.

To all whom it'mag concern:

Be it known that 1, JAMES F. BEZDEGHEOK, a citizen of the United States, residing at Long Beach, in the county of Los Angeles and State of California, have invented a new and useful Look, of which the following is a specification.

This invention relates to looks and refers particularly to a lock adapted for use on doors such as barn or garage doors.

An object of this invention is to provide a lock which may be opened without the use of a key or'other appliance by a party having knowledge of a certain combination to be employed on the lock.

Another object of the present invention is to provide a lock which operates through first an axially shifting movement upon setting certain parts of the lock in proper arrangement after which the lock is operated through a rotary motion to effect the looking or unlocking of the parts or members held by the lock.

Another object of this invention. is to pro vide a combination lock of simple and sturdy construction which operates after the proper setting of the combination in a peculiar combination motion to release the locked door or part.

This invention includes certain novel parts, combination and relation of parts, all

of which will be morefully understood fromthe following description of the accompanying drawings.

The accompanying drawings illustrate-the preferred example of a lock embodying the invention in which Figure 1 is an elevation of a door provided with the lock.

Figure 2 is an enlarged front elevation of the lock with the door removed.

Fig. 3 is a side elevation of the lock being mostly in longitudinal vertical section showing the position of the parts in the locked position.

Fig. 4 is a similar view mainly in longitudinal vertical section showing the lock in the unlocked or open position.

Fig. 5 is a transversevertical section on the line 55 of Fig. 3.

Fig. 6 is a fragmentary bottom view of the outer barrel of: the look.

In the drawings the lock isillustrated .as

comprising a cylindrical barrel 2 preferably having a laterally extending handle 3 at one end, which handle is made integral with vided with a circular flange 6 at one end having a number of pointed lugs 7 which are adapted to be driven in the door 5 to hold the bushing 4 from rotation. "The opposed end of the bushing 4 is engaged by a nut 7 a which abuts the rear side of the door 5 and is preferably provided with means such as the screws 8 for locking the nut from rotation. The bore 9 of the bushing is preferably provided with a shoulder 10 positioned to engage a similar shoulder on the barrel 2 of the lock for limiting the inward motion of the barrel 2 within the lock. The bottom of the barrel 2 is longitudinally slotted from the inner end about one-half the length of the barrel and joining the slot 11 are provided lateral slots 12 and 13 which extend about half of the circumference of the barrel. The bushing 4 is provided with inwardlyextending lugs 14 and 15 which are spaced apart a distance equal to the spacing between the slots 12 and 13 and are of a size to lit the slots 12 and 13 or in the longitudinal slot 11 The inner end of the barrel 2 is provided with a bushing 16 which forms a bearing fora shaft 17 which extends longitudinally through the barrel 2 and is provided at the outer end of the lock with a dialed knob 18. 20 indicates a head on the inner end of the shaft 17 which engages the bushing 16. The shaft 17 carries a cylinder 19 within the barrel 2 which cylinder in the locked position is positioned behind the lug 15 in the bushing 4. The cylinder 19 is provided with a way 21 extending longitudinally through the cylinder which way thus permits the cylinder 19 to pass the lug 15 in the bushing 4 when the cylinder is rotated to align the way 21. with the lug 15. 22 indicates a tubular shaft enclosing part of the shaft 17 and carrying a cylinderr23 disposed so that in the locked position the cylinder 23 will be. positioned behind the lug 14. Said cylinder 23 is likewise provided with a way 24 which upon proper rotation of the cylinder will align with the lug 14 to permit the cylinder 23 to pass said lug. Gutside the barrel 2 the tubular shaft 22 is provided with a circular dial 25 abutting the dial .knob 18 of the shaft 17. 26 indicates a bearing block at the outer end of the barrel 2 for supporting the tubular shaft 22. l

The operation of the lock may now be described. Y

First assuming that the lock is in the position indicated in Fig. 3 where the cylinders 19 and 23 are positioned behind the lugs 14 and 15 respectively. In this position the cylinders 19 and 23 will engage the lugs 14 and 15, respectively unless the ways 21 and 24 are aligned with the lugs. The lugs thus prevent the barrel 2 of the lock and the part supported thereby from being shifted axially outward and the lugs 14 and 15 further prevent rotation of the barrel since in this position such lugs are not aligned with the circular slots 12 and 13 in the barrel. To open the lock the dials 18 and 25 must first be rotated to correctly align the ways 24 and 21 with the lugs 14 and 15 respectively. In this position the lock may then be opened by exerting an outward pull on the handle 3 which will shift the look so that the lugs 14 and. 15 pass into the cylinders 23 and 19 and in line with the ways 12 and 13.

' This motion of the barrel 2" may, if desired, cause the release of the door 5, but preferably the door is released through a partial rotation of the barrel 2 in the outward position. The outward shifting of the barrel 2 brings the lugs 14 and 15 in line with the ways 12 and 13 in the barrel so that the barrel is free to rotate.

The axial and rotary motion of the barrel 2 may cause a release of the door 5 by various latch means and it is n0t,intended to limit the invention in its broad aspect to any particular means for causing these operations of the lock to release the door 5. Preferably, however, as a preferred door latching means the inner end of the barrel 2 carried a head 27 locked thereto such as by the set screw 28. The head'27 is provided with opposed flanges 29 having sliding engagements with horizontal ends 30" the rods 31 from their engagement above and below the door 5 and permit the same to p a While I have described the invention in thereof in one position and operative whenallgned wlth sa1d circular ways to permit rotation of the barrel, and a plurallty of separately controlled members adapted to normally hold the barrel in one position and in a certain position to permit movement of the barrel to the other position,

2. A lock comprising a bushing having a plurality of inwardly directed lugs, a barrel mounted within the bushing and having; a longitudinal slot through which said lugsextend, cross slots in said barrel spaced toreceive said lugs on axial movement of said barrel, cylinders disposed to normally engage said lugs and prevent said axial movement, said cylinders having slots adapted to align with said lugs and permit said cylinders to pass the same, and telescoped means for aligning the lugs with the cylinders.

3. In a combination lock, the combination with a member adapted to actuate a latch by a rotary motion, of a bushing providing sta-- tionary lugs, shiftably mounted cylinders carried by said member and normally ongaging the lugs, thereby restraining said member against axial motion, ways in the cylinders, separate control means carried by said member for aligning the ways with said lugs, thereby permitting the release of said member for axial movement, and means I operative in one position to engage said member andcprevent rotation thereof, and in another axially spaced posit-ion to permit rotation of said member.

I 4. In a device of the class described, the combination of a bushing having a flange at one end with inwardly projecting prongs, a;

member mounted in said bushing, means on one of sa1d parts engaging the other part to prevent'rotary movement in one position and to permit rotary movement in another relative positlon of sa1d parts, means carried by said member to prevent axial motion thereof relative to said bushing, and a plurality of separately controlled means for releasing saidmember for axial mot-ion.

5. In a combination lock, the combination of a bushing for mounting the lock, said bushing having spaced inturned lugs, a'bare rel mounted in said bushingan'd adaptedto engage said lugs in one position so thatrelative rotation between said barrel and said bushing is prevented and formed so that upon axial motion to another position relarelative axial movement between said barrel and bushing, and separately rotatable control means for positioning said members in a releasing position in Whicb relative axial movement between said barrel and bushing is germitted.
